With remarkable progress being reported in living donor liver transplants and small bowel transplantation, the 9th Keio International Symposium for Life Sciences and Medicine was auspiciously timed. Titled "Current Issues in Liver/Small Bowel Transplantation," the Tokyo symposium brought together researchers from Japan and other parts of the world. This volume is a compilation of papers from the symposium, organized into five key areas of interest to medical professionals: Technical aspects and physiological problems in split/living donor liver transplantation; Viral hepatitis and liver transplantation; Current status and future prospects in small bowel transplantation; Liver transplantation for malignant hepatic tumors; and Novel strategies in immunosuppression. Containing the most up-to-date information on these vital issues, the book is an essential resource for all researchers and practitioners concerned with liver and small bowel transplantation.

In Japan, cadaveric donor liver transplantation is not common even though cadaveric organ transplantation was legally established in 1998. In contrast, the number of living donor liver transplantations is increasing, with more than 1700 cases at 43 Japanese institutes by November 2001. Indications for and have become living donor liver transplantation are widening in Japan similar to those for cadaveric donor liver transplantation in the United States and Europe. At the same time, split liver transplantation from cadaveric donors shares some technical aspects with living donor liver transplantation. Remarkable progress has been reported recently, and thus it was an auspicious time to hold a symposium on "Current issues in liver/small bowel transplantation" in Japan. We were honored to hold a very fruitful symposium sponsored by the Keio University Medical Science Fund and to bring together top-rank transplant surgeons from Japan and other countries. It was a productive and rewarding time for all participants. We were able to share our experience through excellent presentations followed by active discussions and insightful com ments. At the symposium, we focused on current issues in liver transplanta tion such as widening indications for viral hepatitis and malignant tumors. We also discussed technical aspects and physiological problems in split/iiving donor liver transplant, novel strategies in immunosuppression, and the current status and future prospects in small bowel transplantation. This book contains the papers from all the distinguished guest speakers, focusing on the topics discussed at the symposium."

A step-by-step guide to the six most important laparoscopic procedures in gastric surgery: fundoplication, gastric banding and resection, gastro-enterostomy, gastrectomy and laparoscopic myotomy for achalasia. Written by an internationally respected group of laparoscopic general surgeons, the book includes an updated overview of indication, pathophysiology, epidemiology and diagnostics. It also covers medical and surgical therapy - both conventional and laparoscopic.

The first goal of this book is to extend Two Minds originating from behavioral economics to the domain of interaction, where the time dimension has to be dealt with rigorously; in human machine interaction, it is of crucial importance how synchronization between conscious processes and unconscious processes is established for a sense of smoothness, and how memory processes and action selection processes are coordinated. The first half this book describes the theory in detail. The book begins by outlining the whole view of the theory consisting of action selection processes and memorization processes, and their interactions. Then, a detailed description for action selection processes theorized as a nonlinear dynamic human behavior model with real-time constraints is provided, followed by a description for memorization processes. Also, implications of the theory to human machine interactions are discussed. The second goal of this book is to provide a methodology to study how Two Minds works in practice when people use interactive systems. The latter half of this book describes theory practices in detail. A new methodology called Cognitive Chrono-Ethnography (CCE) is introduced, which adds the time dimension to Hutchins Cognitive Ethnography, in order to practice "know the users" systematically by designing user studies based on a simulation of users mental operations controlled by Two Minds. The author then shows how CCE has been applied to understanding the ways in which people navigate in real physical environments by walking and by car, respectively, and explores the possibility of applying CCE to predict people s future needs. This is not for understanding how people use interfaces at present but to predict how people want to use the interfaces in the future given they are currently using them in a certain way Finally, the book concludes by describing implications of human machine interactions that are carried out while using modern artefacts for people's cognitive development from birth, on the basis of the theories of action selection and memorization.
